Quick question if you buy Windows 7 Upgrade.
Which operating system can you upgrade from ?
I believe if you are intalling Windows 7 you can not upgrade from Windows XP.
Or it can even get more complicated like if you have Windows Vista Home can you upgrade to Windows 7 Professional or are you only allow to upgrade to Windows 7 Proffesional? or like for like.
Ideally they should tell you which version you need to have.
What if I have Windows 95, 98, Me, etc can I just buy the Upgrade.
I have search the web and could not find an UPGRADE compatibility Matrix?
